sporopollenin

孢粉素

Sporopollenin

孢子体素是植物孢子和花粉粒韧性外壁的主要成分。 它在化学上非常稳定,通常在土壤和沉积物中保存良好。 外层通常以物种特定的模式复杂地雕刻,允许从湖沉积物中回收的材料为古生物学家提供关于过去植物和真菌种群的有用信息。 Sporopollenin也发现了古气候学领域的用途。 孢子体素也被发现在几种绿藻分类群的细胞壁中,包括真菌和小球藻。 由于其不寻常的化学稳定性和抗降解酶和强化学试剂,孢子素的化学成分不是完全知道的。 分析显示生物聚合物的混合物,主要含有长链脂肪酸,苯丙素,酚类和痕量的类胡萝卜素。 示踪剂实验表明苯丙氨酸是主要的前体,但其他碳源也有贡献。 孢子素素可能来自化学交联以形成刚性结构的几种前体。 Sporopollenin is a major component of the tough outer walls of plant spores and pollen grains. It is chemically very stable and is usually well preserved in soils and sediments. The exine layer is often intricately sculptured in species-specific patterns, allowing material recovered from lake sediments to provide useful information to palynologists about plant and fungal populations in the past. Sporopollenin has found uses in the field of paleoclimatology as well. Sporopollenin is also found in the cell walls of several taxa of green alga, including Phycopeltis and Chlorella. The chemical composition of sporopollenin is not exactly known, due to its unusual chemical stability and resistance to degradation by enzymes and strong chemical reagents. Analyses have revealed a mixture of biopolymers, containing mainly long chain fatty acids, phenylpropanoids, phenolics and traces of carotenoids. Tracer experiments have shown that phenylalanine is a major precursor, but other carbon sources also contribute. It is likely that sporopollenin derives from several precursors that are chemically cross-linked to form a rigid structure.

在英语 词典里sporopollenin的定义

字典中孢粉素的定义是在孢子和花粉粒上形成耐久的,化学稳定的外层的材料。

The definition of sporopollenin in the dictionary is the material that forms the durable, chemically stable outer layer on spores and pollen grains.
